Our OpenMV board arrived today from Robotshop. However, when I connect it to the laptop or to an external 5V power supply, none LED lights up and it doesn’t show listed under the /dev/ directory (ls /dev/tty.*). Is it defective? On the back reads:
Mmm, this could be. But, it shouldn’t be. Um, can use attach a wire between the BOOT0 and RST pin and then plug it back into your computer.
The DFU bootloader should appear as a device. If this is the case then you can recover it using the DFU util built-in to the IDE. You’ll just need to install a few command lines tools for this to work. Let me know if the device appears as a DFU bootloader in linux and I’ll tell you how to proceed. If you can’t find the device you can also just try blindly. You’ll need to install these things:
Your suggestion did it “attach a wire between the BOOT0 and RST pin and then plug it back into your computer”. After that I was able to upload the firmware and run the sample programs. Thanks, and good luck with the new KickStarter campaign!
We install the latest version of our firmware with MP. Ibrahim will need to update our code base to the latest MP version. This usually breaks a lot of stuff each time he does this so it’s somewhat avoided if not necessary. For the M7 board we will pull in all MP changes again.
As for the documentation, we should have that updated by next week along with another firmware release. We’re working on getting the QRCode stuff our the door right now analog with a bunch of other changes.
